Modifying the GUI images

[wigout]

This isn't as good as customizing the actual functionality of the media player, but this will permit you to alter what images the DvdPlayer Gui shows on the screen.

First note that the DvdPlayer is picky: it wants to see all the files it expects to see in the Resource/bmp directory. Furthermore, it expects them to be the right resolution. Finally it expects them to be in the special "realtek" bmp format, but will display regular bmps, as well as png's (renamed from .png to .bmp) though there will be a slight delay loading them.

So to start skinning the DvdPlayer gui you need to know the resolutions of the files in the Resource/bmp folder.

This bash one-liner will generate a tab separated list of all the .bmp files it finds in the directory you run it.

echo -e "filename \t width \t height";for f in `ls|grep -ie '.bmp'`; do echo -e "${f} \t" "$((`hexdump -n 4 -s 8 ${f} | cut -c8-12 | sed -e 's/ /0x/'`)) \t" "$((`hexdump -n 4 -s 8 ${f} | cut -c13-17 | sed 's/ / 0x/'`))"; done

run in the Resource/bmp/ directory it will give an output like:

filename         width   height
IMAGE_3POE_WIFI.bmp      45      85
IMAGE_3POE_WIRED.bmp     45      85
IMAGE_ABBAR_TRACK.bmp    782     49
IMAGE_ABERASE_BG.bmp     926     150
IMAGE_ABREPEAT_SETA.bmp          177     90
IMAGE_ABREPEAT_SETB.bmp          177     90
IMAGE_ANGLE.bmp          177     90
IMAGE_ANGLEMARK.bmp      494     84
IMAGE_ANGLEMARK_FOCUS.bmp        494     84

if you want to run it on just one file:

echo -e "width:" $((`hexdump -n 4 -s 8 IMAGE_GBROWSER_BG.bmp | cut -c8-12 | sed 's/ /0x/'`)) " height:" $((`hexdump -n 4 -s 8 IMAGE_GBROWSER_BG.bmp | cut -c13-17 | sed 's/ / 0x/'`))

Just put whatever file or path/file in for IMAGE_GBROWSER_BG.bmp that you want.
Let's say you want to make the background white on the browser screen.
Make a white bmp. make 1280 wide x 720 tall. save it as white.bmp
If you're going to full around like this, you might as well stay organized.

mkdir /tmp/hdd/volumes/HDD1/Resource
mkdir /tmp/hdd/volumes/HDD1/Resource/bmp

then copy your white.bmp over to your /tmp/hdd/volumes/HDD1/Resource/bmp.

To test it out:

mount -o bind /tmp/hdd/volumes/HDD1/Resource/bmp/white.bmp /usr/local/bin/Resource/bmp/IMAGE_GBROWSER_BG.bmp

It reloads the background of the "file broswer" as white.

(NOTE: Have a video loaded as you do this- this "clears" the bmps from the memory of the DvdPlayer gui (I guess) so that it actually reads the new file--- the first time I did it while flipping throw the media player menus and the device choked)


Now the neater thing is you can also convert your own generated bmp's to the realtek native bmp, which compresses the bmp's greatly and removes all lag in image loading.

You need a linux install/virtual machine/live cd to run bmp2felics. it is a 386 (desktop pc processer) program. It won't run on the pbo because it is not a mipsel program.
to do that, download the attached bmp2felics.zip, unzip it.
to run it type:
./bmp2felics [source folder]
where [source folder] is where you have put your own custom bmps
then bmp2felics will generate two new folders:
raw
which contains a minutely altered bmp file
AND
rfc
which contains your converted bmp files.

The converted bmp files are just like the ones in the Resource/bmp folder. The DvdPlayer is the only thing that display them and even then ONLY when all the conditions listed at the top of this post are met- the right names, format, dimensions, and locations.

Anyway, I don't have a terribly pressing desire to actually change the look of the gui, but I know some very well might.

A related project for the pohd can be found here.

Anyway, good stuff.
